JavaScript概述

在HTML中嵌入JavaScript的方法

1.利用<script>标签的language属性

<script language="javascript">

</script>

 

2.利用<script>标签的src属性

<script language="JavaScript" src="aaa.js">
</script>

aaa.js为：

<!--Begin hiding JavaScript
//alert("Hello");
document.write("This text was generated by code in the aaa.js file.")
//End hiding JavaScript-->

 

3.利用onLoad方式

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<script language="javascript">
<!--
function done(){
	alert("This page has finished loading.");
}
//-->
</script>
</head>
<body onLoad="done()">
</body>
</html>

 

在不兼容的浏览器中隐藏JavaScript代码

<!-- 开始隐藏JavaScript

JavaScript声明

//结束 JavaScript隐藏-->
